自然科学学术活动月系列学术讲座（236）

题目： Research in Composite Materials & Structures @ NUS

主讲人：T.E. (Tong-Earn) Tay 教授

时间：2023年11月24日星期五 9：00

地点：23-510

主讲人简介：

T.E. (Tong-Earn) Tay is Professor at the Department of Mechanical Engineering, National University of Singapore (NUS). He leads a research group focussed on multi-scale and multi-fidelity computational modeling of progressive damage, failure, delamination and impact of composites. Professor Tay was formerly Head of Department of Mechanical Engineering (2011-2015) and Vice-Dean for Research for Faculty of Engineering (2009-2011). He is an associate editor for the Journal of Reinforced Plastics & Composites, editorial board member of the Journal of Composite Materials, International Journal of Damage Mechanics, Applied Composite Materials, Multiscale and Multidisciplinary Modeling Experiment and Design, and Journal of Multiscale Modeling. He is a Professional Engineer, Chartered Engineer, Founding Fellow of the Singapore Academy of Engineering (FSAE) and Council Member of the Asian-Australasian Association for Composite Material. Professor Tay is a recipient of the JEC Asia Life Achievement Award. His research has led to more than 185 journal publications, 4 book chapters and 260 conference and seminar presentations (2022). Professor Tay has graduated 19 PhD students and mentored 21 postdoctoral researchers and 10 research engineers. He has also been the principal investigator of research grants from Agency for Science, Technology & Research (A*STAR), Defence Science & Technology Agency (DSTA), Economic Development Board (EDB), Ministry of Education, Marine & Port Authority (MPA), US Air Force Office of Scientific Research (AFOSR) and direct industry funding (Maruhachi, Airbus, Boeing, Rolls-Royce, Vestas, Haliburton, DSM, etc.).

报告摘要：

Besides an introduction to composites related research at NUS, this talk presents recent developments in the multi-fidelity and multi-scale modeling of progressive damage and delamination in fiber-reinforced composites. The main motivation is to preserve fidelity to physics, while keeping computational efficiency and costs at manageable levels. While there have been significant progress in recent years, challenges and unresolved research questions remain, such as the potential of machine learning to model progressive damage accurately without resorting to hi-fidelity (and therefore hi-cost and time-consuming) computational models. The talk also presents some experimental research activities and testing facilities to complement numerical modeling. Finally, an invitation to collaborate with NUS in topics of common interest is extended to interested academic staff and students.

报告摘要：

功能电子晶体在基础研究和应用基础研究方面具有重要的价值，其中的两个典型代表，如超导晶体和碳化硅(SiC)，在最近取得了长足的进步和发展。报告人长期围绕超导单晶和第三代半导体SiC单晶开展生长、物性表征及高精度调控研究，在晶体生长方面：主要利用高温溶液法和气相法等，通过设计助熔剂、生长装置和调控温场分布等制备了多种原创的超导单晶和2-6英寸大尺寸SiC单晶，解决了晶体种类少、缺陷多和良率低等基础性难题；在物性调控方面：利用原位高压和原位电场栅压等物性表征和调控方法，探究了晶体中“功能基元”与物性的精确对应关系，解决了超导电子相图难以精确标定、铁磁SiC大尺寸单晶难以获得等难题，受到国内外同行的正面引用和广泛认可。

报告摘要：

The challenge for 3D in vitro cell culture modelling is the development of appropriate biomaterials that replicate the biological, chemical, and mechanical complexities of the native 3D scenario. Current improvements allow the growth of intelligent biomaterials that can fix the complex features of the extracellular environment in terms of structural support and composition. Silk protein fibroin and sericins are utilized for 3D cell cultures in pure form or by blending with other biomaterials, improving their physiological resemblance (mechanical properties, biodegradability, and biocompatibility). We have designed and investigated how silk protein fibroins and sericins with different formats, like scaffolds, hydrogels, nanofiber electrospun mats, and micro- and macro patterns, support the growth of different types of cells (bone, cartilage, cardiomyocytes, skin, and stem cells) for attachment, proliferation, differentiation, and tissue regeneration, including coculture of disease and normal cells. We show how silk fibroin alone and/or blend supports cancer cell growth. The coculture of cancer cells with fibroblasts and mesenchymal stem cells better mimics the tumour microenvironment and drug response. I will discuss the trends of silk biomaterials for tissue engineering and regenerative medicine.
